BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lupine plant, botanically known as Lupinus hybrid and hereinafter referred to by the name ‘ET LPN 802’.

The new Lupine plant is a product of a planned breeding program conducted by the Inventors in Boijl, The Netherlands. The objective of the breeding program is to develop new compact and freely flowering Lupine plants with a long flowering period.

The new Lupine plant originated from a cross-pollination in August, 2017 of a proprietary selection of Lupinus hybrid identified as code number 7-159, not patented, as the female, or seed, parent with a proprietary selection of Lupinus hybrid identified as code number 2019-23, not patented, as the male, or pollen, parent. The new Lupine plant was discovered and selected by the Inventor in July, 2018 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Boijl, The Netherlands.

Asexual reproduction of the new Lupine plant by in vitro meristem culture in a controlled greenhouse environment in Boijl, The Netherlands since August, 2018 has shown that the unique features of this new Lupine plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Lupine have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ET LPN 802’. These characteristics in combination distinguish ‘ET LPN 802’ as a new and distinct Lupine plant:

-   -   1. Upright and relatively compact plant habit.     -   2. Moderately vigorous growth habit and moderate growth rate.     -   3. Strong and sturdy flower stems.     -   4. Numerous large light yellow-colored flowers arranged on dense         terminal racemes.     -   5. Daylength neutral.     -   6. Good garden performance.

Plants of the new Lupine can be compared to plants of the female parent selection. Plants of the new Lupine differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Lupine are shorter than plants of the         female parent selection.     -   2. Plants of the new Lupine are more freely flowering than         plants of the female parent selection.

Plants of the new Lupine can be compared to plants of the male parent selection. Plants of the new Lupine differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Lupine are more compact and have shorter         internodes than plants of the male parent selection.     -   2. Plants of the new Lupine have smaller leaves than plants of         the male parent selection.     -   3. Plants of the new Lupine are daylength neutral whereas plants         of the male parent selection are daylength dependent.

Plants of the new Lupine can be compared to plants of Lupinus hybrid ‘ET LPN 709’, disclosed in U.S. Plant patent application Ser. No. 17/672,518. Plants of the new Lupine differ primarily from plants of ‘ET LPN 709’ in the following characteristics:

-   -   1. Plants of the new Lupine are taller and broader than plants         of ‘ET LPN 709’.     -   2. Plants of the new Lupine have slightly longer internodes than         plants of ‘ET LPN 709’.     -   3. Plants of the new Lupine have slightly larger inflorescences         than plants of ‘ET LPN 709’.     -   4. Flowers of plants of the new Lupine are light yellow in color         whereas flowers of plants of ‘ET LPN 709’ are purplish red in         color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Lupine plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Lupine plant. The photograph is side perspective view of a typical flowering plant of ‘ET LPN 802’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants of the new Lupine grown during the spring and summer in 26-cm containers in an outdoor nursery in Boijl, The Netherlands and under cultural practices typical of commercial Lupine production. During the production of the plants, day temperatures ranged from 18° C. to 22° C. and night temperatures ranged from 10° C. to 16° C. Plants were one year old when the photograph and the detailed description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
